[Data from systematic electrocardiographic study during exercise in hypertensive patients. Apropos of 307 cases].

The authors report the data of a systematic electrocardiographic study of 307 subjects suffering from hypertension. They analyse the EKG anomalies at rest and after exercise and study the relationships likely to exist between these anomalies and other parameters such as age, blood pressure, etc. They stress the diagnostic but also discriminatory value of this type of investigation in hypertension.
